Google's Transition From Single Datacenter, To Failover, To A Native Multihomed Architecture
http://highscalability.com/blog/2016/2/23/googles-transition-from-single-datacenter-to-failover-to-a-n.html Making a system work in one datacenter is hard. Now imagine you move to two datacenters. Now imagine you need to support multiple geographically distributed datacenters. That's the journey described in another excellent and thought provoking paper from Google: High-Availability at Massive Scale: Building Google's Data Infrastructure for Ads. The main idea of the paper is that the typical failover architecture used when moving from a single datacenter to multiple datacenters doesn't work well in practice. What does work, where work means using fewer resources while providing high availability and consistency, is a natively multihomed architecture. - - - --Lauren-- Lauren Weinstein ([email protected]): http://www.vortex.com/lauren Founder: - Network Neutrality Squad: http://www.nnsquad.org - PRIVACY Forum: http://www.vortex.com/privacy-info Co-Founder: People For Internet Responsibility: http://www.pfir.org/pfir-info Member: ACM Committee on Computers and Public Policy Lauren's Blog: http://lauren.vortex.com Google+: http://google.com/+LaurenWeinstein Twitter: http://twitter.com/laurenweinstein Tel: +1 (818) 225-2800 / Skype: vortex.com I have consulted to Google, but I am not currently doing so -- my opinions expressed here are mine alone. _______________________________________________ pfir mailing list http://lists.pfir.org/mailman/listinfo/pfir
